When one end of the finished product is inserted into the detection hole 11, gas flows. If the feather 8 shakes, the straw leaks, otherwise there is no leakage.

[0019] See also Figure 4 A support plate 20 is installed in the middle of the inner cavity of the cabinet 1. The tops of the two groups of support plates 20 are provided with slide grooves. The front and rear ends of the tops of the two groups of slide grooves are slidably connected with rectangular columns 21. The outer sides of the four groups of rectangular columns 21 are fixedly connected with screw blocks 14. The middle part of the body of the screw block 14 is screwed with a first bolt 15. The front and rear four groups of rectangular columns 21 are connected with lower blocks 19. The upper part of the lower block 19 is slidably connected with an upper block 18. The upper and lower blocks 18 and 19 are provided with mounting holes on the opposite sides. A reset spring is provided inside the mounting hole. The top end of the reset spring is connected to the upper block 18, and the bottom end of the reset spring is connected to the upper block 18. It is connected to the lower block 19, and a slide groove is provided on the top of the support plate 20, so that the four groups of rectangular columns 21, the two groups of lower blocks 19 and the two groups of upper blocks 18 can be moved forward and backward. After reaching the ideal position, the first bolt 15 is rotated to tighten it, so as to adjust the limit distance of clamping the straw. A rod sleeve 22 is provided on the top of the two groups of upper blocks 18, and a bent rod 23 is connected between the openings of the two groups of rod sleeves 22. By grabbing the front end of the bent rod 23 and lifting it, the rod sleeve 22 and the two groups of upper blocks 18 are driven to rise, and the heat-treated straws are placed in the groove holes, the bent rod 23 is loosened, and the reset spring is pulled back to play the function of clamping the straws.

[0020] Among them, the left and right sides of the support plate 20 are connected to support frames 24, and the upper parts of the two groups of support frames 24 are movably connected to the moving blocks 17 on the sides facing each other. A transverse groove is provided on the top of the support frame 24, and the left and right ends of the top of the moving block 17 are screwed with second bolts 16. The second bolt 16 body passes through the transverse groove, and a round hammer 13 is inserted through the middle of the moving block 17 body. A handle 12 is provided on the top of the round hammer 13.

[0021] Working principle: When the new scheme is implemented, the inner cavity of the cabinet 1 is designed with a baking electric box 6. The straight tube billet rolls down from the slope groove 4 to the discharge port 10, passes through the two thin plates 9 that limit the falling space, and falls into the notch of the arc frame 7. The baking electric box 6 performs a heat treatment process on one end of the straight tube billet in the notch of the arc frame 7, causing one end of the straight tube billet to be easily deformed by heat. The front end of the bent rod 23 is grabbed and lifted up. Through the stretching function of the reset spring in the mounting hole on the opposite side of the lower closing block 19 and the upper closing block 18, the upper closing block 18 and the rod sleeve 22 are pulled up, and the straw is placed in the groove. The bent rod 23 is loosened, the reset spring returns to its position, and the upper closing block 18 and the lower closing block 19 are tightened to limit the straw. Take the handle 12 and lift it up, drive the hammer 13, press the handle 12, the hammer 13 squeezes the straw to bend it, and the movable block 17, the rectangular column 21, the lower block 19, and the upper block 18 can be adjusted to move forward and backward through the slide groove on the top surface of the support plate 20 and the horizontal groove on the top of the support frame 24 to reach the ideal position, rotate the first bolt 15 and the second bolt 16 to tighten, and adjust the limit distance of the straw. An air pump 5 is provided on the right side of the inner cavity of the cabinet 1. After the straw is bent and shaped, one end of the straw is inserted into the detection hole 11 in the center of the front side of the air pump 5, and the gas flows. If the straw has cracks, the feather 8 shakes and the finished product leaks. If the feather 8 does not shake, the finished product has good quality.
